ARCHING ACTION IN FRP REINFORCED CONCRETE SLABS

摘要

The corrosion of reinforcement embedded in concrete has been the cause of major deterioration and of high costs in repair and maintenance. Fibre Reinforced Polymers (FRP) exhibit high durability in combination with high strength and light weight. However, the majority of research with FRP bars for reinforcing concrete has been on simply supported beams and slabs where the low value of elasticity of FRP has meant that the service behaviour has often been critical. However, the arching action which occurs in laterally restrained slabs has a beneficial influence on the service behaviour. This paper presents the results of tests on concrete slab with both steel and GFRP reinforcement.
